You can use boost::bind to bind all the arguments and get a nullary functor
back, which you can store in a container as a boost::function. Something
like this (not tested):

void foo(int i, string s) { ... }

typedef boost::function<void (void)> func_t;
std::vector<func_t> v;
func_t a_function = boost:bind(&foo, 1, "fred");
v.push_back(a_function);

... then later ...

func_t a_function = v.front();
a_function(); // <- invoke foo(1, "fred");
